Joyce Is a Well-Organized Student and Plans Her Activities as Well

Joyce is a well-organized student and plans her activities as well as her studying in advance. Joyce knows that she has a history exam next Friday, so she plans to sleep 4 hours on Wednesday night, 4 hours on Thursday night, and then to sleep 16 hours on Friday night to make up the missed sleep. Researchers know that Joyce's plan:

A) is faulty because we do not make up all of the sleep time we have lost.
B) will work because young adult college students need only 4 hours of sleep per night.
C) is faulty because it is unlikely that a young adult college student can sleep 16 hours straight.
D) will work because people do not show signs of sleep deprivation for at least three days so her test performance will not suffer.
